vin a plurality of helical windings seated one within the other, and connected in parallel, in eliminatingl the iron core commonly employed, and in the construction of the frame of refractory insulating material which in closes and holds said windings;

In the accompanying drawings- Figure l is an elevation of my reactor. Fig. 2 is a top view. Fig. 3 is horizontal section on the line fr, a: of' Fig. l. Fig. el is a similar section cn the line y, y/ of Fig. l. Fig. 5 section on line a, e ot Fig. l. Fign 6 is an arge-.d detail view showing in section' the inode of connecting the terminals to the ends of the coils.

Similar numbers and letters of reference indicate like parts.

l, 2, 3, si, 5, 6, 7, 8, 9, l0 are concentric helical coils ci wire disposed one within the other and separated by spacers A oft-insulatine material. The un er ends ofi said coils are connected to termina-l B, and the lower ends to terminal C, so that said coils are connected in parallel between said conductors B and The terminals B and C are preicrably bars of polygonal cross section having-openings to receive the ends of the coils, which ends may be sweated in said openings, as indicated in Fig. 6.

In order to support and -liold the coils, l provide the following construction.

E and F are top and bottom header plates of porcelain or other refractory insulating material, each having a. central opening G.

Upon the bottom vheader F and at the cor-` ners thereof are placed four porcelain blocks H, each having an extension preferably e12- tending inwardly to the opening in said header. The coils l to l0 rest upon said Specicaton of Letters Patent.

blocks H. Above the coils are placed four porcelain blocks J, similar to blocks H, and above the blocks J is the top header AE. Between the blocks H and J and iilling the intervening space are porcelain spacing blocks K, piled one above the other. At each corner of the headers are bolts L which eX- tend through blocks H and J andthe spacing blocks K, thus completing the frame or crate, binding all parts thereo'lI together, and clamping the coils l to 10 therein. On

the under side of top header E and on the' upper side of bottom header F are secured barslVl, N of insulating material, through which pass respectively theterminals B, C. Said bars are cut away to permit the ends of the coils l to lO'to be connected to said terminals in the manner already described.

The object of providing a number of helical coils connected in multiple is to eliminate. 'Foucault losses/which would occur if a single coil of large cross sectional area were used. rlhe object et separating the individual coils at intervals by spacers A is to form vertical ventilating air spaces between them.' The receiving and supporting frame .may have its sides closed by sliding doors O ci porcelain or the like inserted in grooves in the spacing blocks K, and all oi its parts in contact with the coils are of insulatingA refractory material.
